l TEU nTihllErci PATENT @FFIOEQ HARRY H. SCHROYER, OF CHICAGO, ILLINOIS,ASSIGNOR' TO TI-IE .ACME SUPPLY COMPANY, A CORPORATION OF ILLINOIS.

sAsH-srnme- To all whom it may concern:

Be it known that I, Hanny H. Sor-ritorna, a citizen of the UnitedStates, and a resident of the city of Chicago, in the county of Cook andState of Illinois, have invente@ certain new and useful Improvements inifiaslrtprings;.and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, and to the numbers of reference marked thereon,which form a part of this specification.

lt is an object of this invention to provide means insertible in thesliding sash of a' window adapted to contact the fixed 'weatherstripping means on the frame to maintain the complemental engaging meanssecured on the sash in close contacttherewith.

It is also an object of this invention to provide a device adapted to besecured in practically any position in the stile of the `window sash andaffording means preventing rattling of the sash in the frame.

It is also an obJect of this invention to provide a device in which theactuating'elements are inclosed within interlitting` casings and therebythoroughly protected.

It is also an object of this invention to provide a sliding membercapable of slightly differential movement to enable the same to readilyadapt itself to inequalities of an uneven Surface..

It is also anfobject of this invention to providea device in which theelements are retained in properv relation by means of a singleremovabley pin.

It is furthermore an object of 'this invention to construct adevice inwhich the slidable casing is capable of slight diiferential movementandis actuated by springsl at each end thereof. p y

It is furthermore an object of this inven` tion to provide a device inwhich' all the elements thereof are loosely engaged therein and thewhole maintained together by means of a single pin. Y y

It is iinally an object of this invention to provide a deviceconstructed of simple metal stamping of durable construction, and whichmay be assembled and installed by persons not having previous experiencewith the same.

The invention (in' a preferred form) consists in the matters hereinafterdescribed and more fully pointed out and defined in the appended claims.

Specification of Letters Patent. Patentd Jun@ i917, Application filedMarch l12, 1913. Serial No. 753,767. i

In the drawings:

Figure l is a vertical transverse section taken through a. car window,the sashes of which are equipped 'with a. device embodying theprinciples of my invention.

Fig. 2 is a transverse horizontal section taken on line Q-Zof Fig. l,showing a con struction of the window post and the relative position andoperation of the sash frame.

Fig. is a front elevation of a device shown attached toa window sash.

i Fig. a is a vertical section online Ll-i of Fig. 3. y

Y Fig. 5 is a horizontal section on line 5-5 of Fig. `l.

As shown in the drawings:

Referring to Fig. l, the reference numeral l, designates an outersliding sash of a car window, of which the inner sliding sash is denotedby the reference numeral 2. The window'is provided with inner and outertransom lights 3 and 4, respectively, which are oii'set on each side ofsaid sliding sashes l and 2, to permit thel same to be raised upwardlybetween said transom lights when it .is desired to open thewindow. Thewindow post comprises a T bar 5, which has rigidly secured to theiianges thereof, inner and outer channels G, and 7, respectively, saidchannels ubeing of unequal width so as to receive the extremities of acontinuous jamb and cheek. plate S, therebetween.

As shown, the outerA channel or cheek plate 7, is provided at the endsof its side iianges with laterally' extendingrflanges 9, which engage ina suitable recess in the stiles of the outer sash l. The recess in theouter sash l, is'provided byrabbeting the outer edge. of the stile in a;stepped manner, and securing therein and flush with the outer face ofthe stile, a small T bar or strip of metal l0.

The cheek plate 8 extends inwardly on each side, thereby affording theside walls and end wall of the windowpost. Said cheek plate isprovidedf4 with longitudinally disposed parallel recesses in they sidewalls thereof, the walls of. said recesses being acutely angled inconverging relation, and

vas clearly shown in Fig. 2, the rear surface of the metal forming thebottom of the recesses ll, have secured thereto, by spot welding orotherwise, the Z bars l2, which are rigidly connected to the T bar 5.

Resilient metallic inner sash stops 13, are

shown engaged in the recesses 11, and stops through for attachment. Acup member 19,Y

is shown inverted in the casing-16, the outside dimensions of said cupmember being slightly less than the inside dimensions of said casing 16,to permit a small amount of differential movement of the cup membertherein, and to insure easy sliding of the saine. The depth of the cupmemberis a trifle less than that of the casing member 16, so that thecup may be depressed within the casing flush with flanges 17, thereof.Said cup membery is provided in the side walls thereof withtransverseslots 20, which are centrally positioned and adapted to correspond withthe apertures inthe sidewalls of the casing 16.

A small pin 21, is inserted through the apertures in the casing 16, andthe slots 20, of the cup member 19, to engage the cup member and casingtogether in sliding relation. For the purpose of normally pressing saidcup member outwardly, spiral springs 22, are loosely engaged betweensaid members at each end thereof, and in order to maintain said springsin proper position,

a channel shaped bridge member 23,' is sprung within the cup member 19,and extends from the bottom thereof, to a point flush with the edges ofthe'side walls.

The operation is as follows:

As shown in the drawings, theV device ras connected in the window sashis adapted to bearV against the fixed weather stop flange 9, therebythrusting the sliding sash inwardly and bringing the members 9 and 10,into close contact 'to effect a seal. Inasmuch as the cupV member 19, isslightly i smaller than the interior of the casing 16,

and isl retained therein by the single pin `21, a small amount ofpivotal movement isv to assume differentialpositions. The amplitudeofmovementof said cup members is of course limited by the length of theslot 20. As shown more particularly in Figs. 3 kand 4c, the 'ends andouter edges of the YcupV member are rounded to facilitate op- Yerationof the device.

Of couise, 1 amk aware that details ofconstruction and operation may bevaried with-i yout departing from the principlesl of my invention, and 1therefore do notpui-pose limiting thepatent granted otherwise thannecessitated' by the prior art.

l claim as my invention: 1. 1n a device of the class described looselyinterfitting cup members one inverted within 'the other, one member apertured and the other slotted in Vboth of the side walls of each thereof,a pin engaged in said apertures and slots to retain said inemberstogether, springs loosely engaged in` each end of said iiiterfittingmembers, and a bridge member sprungwithin one of said cup membersadapted to space Vsaid springs in proper relation.

2. 1n a device of the class described, cup members, spiral springs, apin holding said members engaged to one another, and means bridging saidpin sprung within one of said membersV adapted to space said springs inproper relation.

3. ln a device of the class described the Y p combination with a windowsash, ofy a cup member disposed longitudinally thereof and recessedthereinto, another cup member inverted thereinto and having a slidingrelation therewith, said first mentioned cup member having aperturestherein and said second mentioned cupmember having slots thereindisposed to register with said apertures, a pin extending transverselythrough said interfitting cup members engaged in the apertures of theone and also in the slots of the other of said cup members, spiral`springs disposed at each end of said interfitting` cup members bearingagainst each thereof to normally impel thesame apart, and a spacingmember mounted within said second mentioned cup member to maintain saidsprings properly positioned with respect to one another.

4t. ln'a device of the class described interfitting cup members, the onehaving slots therein and the Vother having apertures therein, a pinextending transversely through said cup members engaging through saidrespective slots and apertures to permit a 'simultaneous' pivotal andsliding movement of one of said cupmembers with respect tothe other,springs disposed within said cup members acting normally te resistpivotal Yand sliding movement therebetween, and means' bridging said pinto hold said springs in position.

In witness whereof I have hereuntoV subscribed my name in the presenceof two subscribing witnesses. Y
